Chapter 10 Viewing Model Information, Status, and Statistics on the Cisco Unified IP Phone
Status Menu
Video Statistics Screen
You can access the Video Statistics screen (see Table 10-5) on the phone to display counters, statistics
of the most recent call.
Note You can also remotely view the video statistics information by using a web browser to access
the Streaming Statistics web page. This web page contains additional RTCP statistics not
available on the phone. For more information about remote monitoring, see
Chapter 11,
“Monitoring the Cisco Unified IP Phone Remotely.”
A video stream is a frame stream between two endpoints. If one endpoint pauses the video streaming,
the video stream stops even though the call is still connected. When the video streaming resumes, a new
video frame stream begins, and the new video data overwrites the former video data.
To display the Video Statistics screen for information about the latest video stream, follow these steps:
Procedure
Step 1 Press the Applications button.
Step 2 Select Administrator Settings.
Step 3 Select Call Statistics.
Step 4 Select Video.
The Video Statistics screen displays these items (Table 10-6):
Severely Conceal Secs Number of seconds that have more than 5 percent concealment events
(lost frames) from the start of the voice stream.
Latency Estimate of the network latency, expressed in milliseconds. Represents
a running average of the round-trip delay, measured when RTCP
receiver report blocks are received.
